The geology of the Kolob Canyons area includes nine known exposed formations, all visible and representing about 150 million years of mostly Mesozoic-aged sedimentation. Part of the Grand Staircase, the formations exposed in the Zion and Kolob area were deposited in several different environments that range from warm shallow seas, streams, and lakes to large deserts and dry near-shore environments.

Yosemite became a National Park in 1890, and contains the world's three largest monoliths of exposed granite. The granitic rocks that form Half Dome and other spectacular park features represent crystallized unerupted magma later exposed by deep erosion and glaciation.
